Abstract:
In March 2026, the Northern Hemisphere polar vortex exhibited a dipole pattern and was stronger than normal. The mid- to high-latitude circulation showed an anomalous four-wave pattern, and the circulation over Asia was relatively zonal. Positive geopotential height anomalies dominated nearly the entire Eurasian Continent. The western Pacific subtropical high was close to the climatological average, and the southern branch trough was intermittently active. The average temperature across China was 5.9℃, 1.2℃ higher than that in the same period of normal years. The national average precipitation was 35.3 mm, which was 19.6% above the normal level for the same period. Precipitation was abnormally more than normal in southern North China, Northwest China and central-western Xizang, but less in Northeast China, Jiang-Huai Region, eastnorthern and central-southern of Jiangnan Region and most parts of South China. During this month, there were two cold air processes, one sand-dust weather process and the first large-scale severe convective weather process of the year in China. Fog events occurred frequently over offshore and land-sea adjacent areas, and also over sea surface. Persistent rainy weather was significant in southern China.
